TECHNICAL FIELD

The present invention relates to personal care compositions comprising a copolymer complex and a volatile, hydrophobic solvent component for solubilizing or dispersing the copolymer complex. The copolymer complex is formed by complexing a fatty amine with a copolymer, wherein the copolymer comprises a hydrophobic monomer, a hydrophilic monomer such that at least 1%, by weight of the total copolymer, comprises hydrophilic monomers bearing acidic functional groups and, optionally, a hydrophobic macromonomer.

BACKGROUND OF THE INVENTION

The rheological, holding, and film-forming properties of polymers and copolymers have contributed immensely to their usefulness in a wide variety of personal care compositions. Products containing such polymers and copolymers include hairsprays, shampoos, hair conditioners, skin creams and lotion, make-up products, antiperspirants and deodorants, shaving creams, topical drug compositions, sunscreen products, and the like. Consumers are constantly seeking products providing improved performance benefits. In their quest to improve upon current products and to create new products, scientists and formulators are continually seeking to develop new key ingredients for such products.

Because polymers play such an important role in the formulation of many personal care products, a need exists for new polymers having new and useful properties. In the hair care area, for example, style retention is generally accomplished by application of either permanent chemical alteration products or temporary styling products. A permanent chemical alteration product, which is commonly referred to as a "hair perm," typically involves treating the hair with various sulfur-containing compounds in order to break the disulfide bonds in the hair fibers, thereby enabling one to alter the shape and orientation of the hair fibers. However, hair perm products have the disadvantage of being harsh and damaging to the hair, and of being long-lasting and difficult to reverse. Conversely, temporary styling products generally do not break the chemical bonds in the hair fibers. These temporary styling products typically are in the form of gels, lotions, mousses, or sprays containing polymeric resins or gums for coating the hair fibers and bonding them together. Many temporary styling products are inconvenient to use and have the disadvantage of not allowing one to readily restyle the hair after the initial application and styling is completed, without further application of additional product. It would be preferable to deliver styling and hold benefits using rinse-off products such as conditioners and shampoos. These types of rinse-off products, however, require styling agents that are substantive to the hair and not readily removed during the rinsing process. Especially useful styling and hold agents for rinse-off compositions are hydrophobic polymeric materials. Such hydrophobic materials, however, may cause a buildup of an unsightly visible residue on the hair with repeated usage. This residue can eventually completely surround the hair shaft and can be difficult to remove with normal shampooing. A need, therefore, exists for improved compositions for providing temporary styling and hold of human hair without the residue and negatives often associated with such compositions.

It has surprisingly been found that hair care products comprising a copolymer complex comprising a copolymer having at least one acid functional monomer and at least one fatty amine complexed with the acid functional monomer provide excellent temporary styling and hold benefits in addition to improved "wash off" characteristics. The copolymer complex of the present invention is soluble or dispersible in and readily deposited by hydrophobic solvent components, yet easily washed away by aqueous surfactant solutions. These compositions can be made into any of a number of conventional forms including, but not limited to, shampoos, conditioners, mousses, gels, lotions, sprays and the like.

In addition to the afore-mentioned hair care benefits, it has been found that the copolymer complex and volatile, hydrophobic solvent component of the present invention are also useful for incorporation into a wide variety of cosmetic and pharmaceutical compositions for topical application to the skin. These materials provide topical compositions which are more easily and uniformly spread upon the skin, which feel good upon the skin, and yet are highly substantive. Furthermore, these compositions are useful for providing occlusion to enhance the penetration of a wide variety of cosmetic and pharmaceutical actives into the skin, or alternatively, through the skin for systemic delivery.

The compositions of the present invention comprise a copolymer complex and a volatile, hydrophobic solvent component suitable for application to the hair or skin. The copolymer complex comprises a copolymer having at least one acid functional monomer and at least one fatty amine complexed with the acid functional monomer.

It is therefore an object of the present invention to provide copolymer complexes having improved solubility or dispersibility characteristics.

It is another object of the present invention to provide copolymer complexes that are soluble or dispersible in hydrophobic solvent components, and yet are readily washed away by aqueous surfactant solutions.

It is another object of the present invention to provide personal care compositions in the form of hair care compositions having improved styling and/or hold properties and having improved aesthetics.

It is another object of the present invention to provide personal care compositions in the form of topical cosmetic and pharmaceutical compositions useful for delivering and retaining a wide variety of cosmetic materials and pharmaceutical actives to and/or through the skin.

It is another object of the present invention to provide rinse off compositions useful for styling and holding hair.

It is another object of the present invention to provide methods for styling and holding the hair.

It is another object of the present invention to provide methods for delivering and retaining to the skin cosmetic materials and pharmaceutical actives.

These and other objects will become readily apparent from the detailed description which follows.

DETAILED DESCRIPTION OF THE INVENTION Essential Components

The compositions of the present invention comprise a copolymer complex and a volatile, hydrophobic solvent component suitable for application to the hair and skin, wherein the copolymer complex comprises a copolymer complexed with a fatty amine.

The copolymers of the present invention can include graft copolymers. The term "graft copolymers" is familiar to one of ordinary skill in polymer science and is used herein to describe the copolymers which result by adding or "grafting" a polymeric chemical moiety (i.e. "grafts") onto another polymeric moiety commonly referred to as the "backbone". The backbone typically has a higher molecular weight than the grafts. Thus, graft copolymers can be described as polymers having pendant polymeric side chains, and as being formed from the "grafting" or incorporation of polymeric side chains onto or into a polymer. The polymer to which the grafts are incorporated can be homopolymers or copolymers. The graft copolymers are derived from a variety of monomer units.

The copolymers of the present invention can be prepared from the copolymerization of monomer units and macromonomer units such that the macromonomer units are "grafted" or incorporated into the resulting copolymer. The term "macromonomer" is a term familiar to one of ordinary skill in polymer science, and is used to described a polymeric material containing a polymerizable moiety. In other words, a macromonomer is a macromolecular monomer, which is essentially a high molecular weight type of monomer building block unit which can be used in a polymerization reaction to form polymers with itself, with other monomers, or with other macromonomers.

The term "hydrophilic" is used herein consistent with its standard meaning of having affinity for water, whereas "hydrophobic" is used herein consistent with its standard meaning of lacking affinity for water. As used herein in relation to monomer units and polymeric materials, including the macromonomers, copolymers, and solvents for the copolymers, "hydrophilic" means substantially water soluble. "Substantially water soluble" shall refer to a material that is soluble in distilled (or equivalent) water, at 25° C. at a concentration of 0.2% by weight, and are preferably soluble at 1.0% by weight. In contrast, "hydrophobic" means substantially water insoluble. In this regard, "substantially water insoluble" shall refer to a material that is not soluble in distilled (or equivalent) water, at 25° C. at a concentration of 0.2% by weight, and preferably not soluble at 0.1% by weight.

The term "soluble" or "solubility" as used herein, means the capability of a substance to form a solution, i.e., either a true solution or a colloidal solution. A true solution being a uniformly dispersed mixture at the molecular or ionic level, of one or more substances (the solute) in one or more substances (the solvent). These two parts of a solution are called phases. A colloidal dispersion is often called a solution. Since colloidal particles are larger than molecules it is strictly incorrect to call such dispersions solutions; however this term is widely used in the literature. The term "dispersible" or "dispersibility" as used herein, means the capability of a substance to form a dispersion, i.e., a two-phase system where one phase consists of finely divided particles (often in the colloidal size range) distributed throughout a bulk substance, the particles being the disperse or internal phase and the bulk substance the continuous or external phase.

The term "rinse-off or wash off" is used herein to mean that the compositions of the present invention are used in a context whereby the composition is ultimately rinsed or washed from the hair and/or skin either after or during the application of the product. Nonlimiting examples of rinse-off products of the present invention include hair conditioners, shampoos and soaps.

The term "substantive" or "substantivity" as used herein, means the binding or retention of a chemical or pharmaceutical active to the surface layer of the stratum corneum or to hair.

The term "suitable for application to human hair and skin" as used herein, means that the compositions or components thereof so described are suitable for use in contact with human hair and the scalp and skin without undue toxicity, incompatibility, instability, allergic response, and the like.

The aforementioned definitions shall also apply to other materials so described herein, to the extent any other definitions regarding such materials are consistent with those stated above.

The compositions of the present invention comprise the following essential components.

Copolymer complex

The hair and skin care compositions of the present invention comprise from about 0.25% to about 30%, preferably from about 2% to about 15%, and more preferably from about 2% to about 10%, by weight, based on the weight of the hair and skin care composition, of a copolymer complex. The copolymer complex comprises a copolymer having at least one acid functionalized monomer complexed with a fatty amine.

Copolymer

The copolymer complex of the present invention comprises from about 35% to about 99%, preferably from about 40% to about 90%, and more preferably from about 50% to about 70%, by weight, based on the weight of copolymer complex, of a copolymer. Based on the weight of the overall hair and skin care composition, the copolymer comprises from about 0.1% to about 10%, preferably from about 1% to about 5%, and more preferably from about 1.5% to about 3.5%, by weight.

The copolymers of the present invention have a weight average molecular weight, in grams/mole, of at least about 10,000. There is no upper limit for molecular weight except that which limits applicability of the invention for practical reasons, such as viscosity, processing, aesthetic characteristics, formulation compatibility, etc. The weight average molecular weight is generally less than about 5,000,000, more generally less than about 2,500,000, and typically less than about 1,500,000. Preferably, the weight average molecular weight is from about 10,000 to about 5,000,000, more preferably from about 50,000 to about 2,000,000, even more preferably from about 75,000 to about 1,000,000, and most preferably from about 75,000 to about 500,000.

The copolymers of the present invention are formed from the copolymerization of randomly repeating A monomer units and B monomer units, preferably wherein the A monomers are polymerizable, ethylenically unsaturated monomers selected to meet the requirements of the copolymer. By "polymerizable", as used herein, is meant monomers that can be polymerized using any conventional synthetic techniques. Monomers that are polymerizable using conventional free radical initiated techniques are preferred. The term "ethylenically unsaturated" is used herein to mean monomers that contain at least one polymerizable carbon-carbon double bond (which can be mono-, di-, tri-, or tetra-substituted). The B monomer units are hydrophilic monomers which are copolymerizable with A and selected from polar monomers, preferably having a Tg or a Tm above about -20° C., and wherein at least about 1%, by weight of the copolymer, of the B monomer units are selected from B monomer units having at least one acid functional group. The A monomer and B monomer units form what is termed the backbone of the polymer and can be selected from a wide variety of structures as long as the copolymer has the required properties and meet the molecular weights and other requirements described herein. The copolymers of the present invention may optionally incorporate C macromonomer units. The C macromonomer units are selected from at least one polysiloxane-containing macromonomer unit which contains a polymeric portion and a moiety copolymerizable with the A monomer and the B monomer. The C macromonomer units form hydrophobic side chains on the copolymer.

The copolymers are prepared by the polymerization combination of A and B monomers and can be characterized by the weight percent of the monomers charged to the reaction vessel in which the polymerization reaction is run. C macromonomers may be optionally incorporated into the polymerization reaction.

As will be clear to one skilled in the art and especially from the Examples, the copolymer may have one or more hydrophobic side chains grafted to the backbone. As known in the art, synthetic graft copolymerization processes may produce a mixture of polymer molecules containing no, one, or more than one hydrophobic side chains covalently bonded to and pendant from the polymeric backbone. From knowledge of the amount and number average molecular weight of hydrophobic side chains in a polymer sample, and the number average molecular weight of the polymer sample, it is possible to calculate the average number of hydrophobic side chains per polymer backbone.

The copolymer complex of the present invention, when dried to a film having 0.5% or less of the volatile hydrophobic solvent component, preferably have a Tg or Tm of at least about -20° C., more preferably at least about 20° C., so that the copolymers are not unduly sticky, or "tacky" to the touch. As used herein, the abbreviation "Tg" refers to the glass transition temperature of the backbone of the polymer, and the abbreviation "Tm" refers to the crystalline melting point of the backbone, if such a transition exists for a given polymer. Preferably, both the Tg and the Tm, if any, are above about -20° C., more preferably above about 20° C.

The grafted copolymers should satisfy the following criteria:

(1) the polymeric side chain portion is covalently bonded to the backbone portion; and

(2) the number average molecular weight of the polymeric side chain portion is from about 1,500 to about 50,000.

The copolymers of the present invention are prepared by the polymerization combination of A monomers and B monomers. C macromonomers may optionally be incorporated into the polymerization process. The copolymers can be synthesized by free radical polymerization of the monomers and macromonomers. The general principles of free radical polymerization methods are well understood. See, for example, Odian, "Principles of Polymerization", 3rd edition, John Wiley & Sons, 1991, pp. 198-334. The desired monomers and macromonomers are all placed in a reactor, along with a sufficient amount of a mutual solvent so that when the reaction is complete the viscosity of the reaction is reasonable. Undesired terminators, especially oxygen, are removed as needed. This is done by evacuation or by purging with an inert gas, such as argon or nitrogen. The initiator is introduced and the reaction brought to the temperature needed for initiation to occur, assuming thermal initiators are used. Alternatively, redox or radiation initiation can be used. The polymerization is allowed to proceed as long as needed for a high level of conversion to be achieved, typically from a few hours to a few days. The solvent is then removed, usually by evaporation or by precipitating the copolymer by addition of a nonsolvent. The copolymer can be further purified, as desired.

As an alternative to a batch reaction, the copolymer can be made by a semi-continuous or continuous process. In the semi-continuous process, two or more additions of monomers or macromonomers are made during the polymerization reaction. This is advantageous when the copolymer is made of several monomers which react during the polymerization at different rates. The proportions of monomers added to the reaction at the separate points of addition can be adjusted by one of ordinary skill in the art such that the polymers of the final product have a more uniform structure. In other words, the polymers of the final product will have a more consistent monomer content distribution for each of the monomer types charged to the reaction.

No. 5,104,646, Bolich et al., issued Apr. 14, 1992, all of which are incorporated by reference herein in their entirety.

The copolymer composition is characterized by the amount of each monomer charged to the polymerization reaction vessel, or alternatively used in a continuous or semi-continuous process.

By appropriate selection and combination of the particular monomer units and macromonomer units, and by the choice of specific relative ratios of the units well within the ability of one of ordinary skill in the art, the copolymers can be optimized for various physical properties and for compatibility with other ingredients commonly used in hair care applications.

Either a single type of A monomer unit or combinations of two or more A monomer units can be utilized. The A monomers are selected to meet the requirements of the copolymer. Preferably, the A units are soluble or dispersible in the volatile, hydrophobic solvent component. By "copolymerizable", as used herein, is meant that the A monomer can be reacted with or polymerized with the B monomers or C macromonomers in a polymerization reaction using one or more conventional synthetic techniques, such as ionic, emulsion, dispersion, Ziegler-Natta, free radical, group transfer or step growth polymerization. In the present invention, monomers and macromonomers that are copolymerizable using conventional free radical initiated techniques are preferred.

Typically, the number average molecular weight of the C macromonomer is from about 1,500 to about 50,000.

Polysiloxane C macromonomers are exemplified by the general formula:

The optional Carriers and additional components vary with the product type and can be routinely chosen by one skilled in the art. The following is a description of some of these carriers and additional components.

Hair Care Compositions

The hair care compositions of the present invention can comprise a carrier, or a mixture of such carriers, which are suitable for application to the hair. The carriers are preferably present at from about 0.5% to about 99.5%, preferably from about 5.0% to about 99.5%, more preferably from about 10.0% to about 98.0%, of the composition. As used herein, the phrase "suitable for application to hair" means that the carrier does not damage or negatively affect the aesthetics of hair or cause irritation to the underlying skin.

Carriers suitable for use with hair care compositions of the present invention include, for example, those used in the formulation of hair sprays, mousses, tonics, gels, shampoos, conditioners, and rinses. The choice of appropriate carrier will also depend on the particular copolymer to be used, and whether the product formulated is meant to be left on the surface to which it is applied (e.g., hair spray, mousse, tonic, or gel) or rinsed off after use (e.g., shampoo, conditioner, rinse).

The carriers used herein can include a wide range of components conventionally used in hair care compositions. The carriers can contain a solvent to dissolve or disperse additional copolymers being used, with water, the C1-C6 alcohols, and mixtures thereof being preferred; and water, methanol, ethanol, isopropanol, and mixtures thereof being more preferred. The carriers can also contain a wide variety of additional materials including, but not limited to acetone, hydrocarbons (such as isobutane, hexane, decene), halogenated hydrocarbons (such as Freons), linalool, esters (such as ethyl acetate, dibutyl phthalate), and volatile silicon derivatives (especially siloxanes such as phenyl pentamethyl disiloxane, methoxypropyl heptamethyl cyclotetrasiloxane, chloropropyl pentamethyl disiloxane, hydroxypropyl pentamethyl disiloxane, octamethyl cyclotetrasiloxane, decamethyl cyclopentasiloxane, cyclomethicone, and dimethicone having for example, a viscosity at 25° C. of about 2.5 centipoise or less), and mixtures thereof. When the hair care composition is a hair spray, tonic, gel, or mousse the preferred solvents include water, ethanol, volatile silicone derivatives, and mixtures thereof. The solvents used in such mixtures may be miscible or immiscible with each other. Mousses and aerosol hair sprays can also utilize any of the conventional propellants to deliver the material as a foam (in the case of a mousse) or as a fine, uniform spray (in the case of an aerosol hair spray). Examples of suitable propellants include materials such as trichlorofluoromethane, dichlorodifluoromethane, difluoroethane, dimethylether, propane, n-butane or isobutane. A tonic or hair spray product having a low viscosity may also utilize an emulsifying agent. Examples of suitable emulsifying agents include nonionic, cationic, anionic surfactants, or mixtures thereof. Fluorosurfactants are especially preferred, particularly if the product is a hair spray composition and most especially if it is a spray composition having relatively low levels of volatile organic solvents, such as alcohols, and relatively high levels of water (e.g., in excess of about 10%, by weight water). If such an emulsifying agent is used, it is preferably present at a level of from about 0.01 % to about 7.5% of the composition. The level of propellant can be adjusted as desired but is generally from about 3% to about 30% of mousse compositions and from about 15% to about 70% of the aerosol hair spray compositions.

Suitable spray containers are well known in the art and include conventional, non-aerosol pump sprays i.e., "atomizers," aerosol containers or cans having propellant, as described above, and also pump aerosol containers utilizing compressed air as the propellant. Pump aerosol containers are disclosed, for example, in U.S. Pat.

These crosslinked polymers contain one or more monomers derived from acrylic acid, substituted acrylic acids, and salts and esters of these acrylic acids and the substituted acrylic acids, wherein the crosslinking agent contains two or more carbon-carbon double bonds and is derived from a polyhydric alcohol. The preferred polymers for use herein are of two general types. The first type of polymer is a crosslinked homopolymer of an acrylic acid monomer or derivative thereof (e.g., wherein the acrylic acid has substituents on the two and three carbon positions independently selected from the group consisting of C₁₋₄ alkyl, --CN, --COOH, and mixtures thereof). The second type of polymer is a crosslinked copolymer having a first monomer selected from the group consisting of an acrylic acid monomer or derivative thereof (as just described in the previous sentence), a short chain alcohol (i.e. a C₁₋₄) acrylate ester monomer or derivative thereof (e.g., wherein the acrylic acid portion of the ester has substituents on the two and three carbon positions independently selected from the group consisting of C₁₋₄ alkyl, --CN, --COOH, and mixtures thereof), and mixtures thereof, and a second monomer which is a long chain alcohol (i.e. C₈₋₄₀) acrylate ester monomer or derivative thereof (e.g., wherein the acrylic acid portion of the ester has substituents on the two and three carbon positions independently selected from the group consisting of C₁₋₄ alkyl, --CN, --COOH, and mixtures thereof). Combinations of these two types of polymers are also useful herein.

In the first type of crosslinked homopolymers the monomers are preferably selected from the group consisting of acrylic acid, methacrylic acid, ethacrylic acid, and mixtures thereof, with acrylic acid being most preferred. In the second type of crosslinked copolymers the acrylic acid monomer or derivative thereof is preferably selected from the group consisting of acrylic acid, methacrylic acid, ethacrylic acid, and mixtures thereof, with acrylic acid, methacrylic acid, and mixtures thereof being most preferred. The short chain alcohol acrylate ester monomer or derivative thereof is preferably selected from the group consisting of C₁₋₄ alcohol acrylate esters, C₁₋₄ alcohol methacrylate esters, C₁₋₄ alcohol ethacrylate esters, and mixtures thereof, with the C₁₋₄ alcohol acrylate esters, C₁₋₄ alcohol methacrylate esters, and mixtures thereof, being most preferred. The long chain alcohol acrylate ester monomer is selected from C₈₋₄₀ alkyl acrylate esters, with C₁₀₋₃₀ alkyl acrylate esters being preferred.

The crosslinking agent in both of these types of polymers is a polyalkenyl polyether of a polyhydric alcohol containing more than one alkenyl ether group per molecule, wherein the parent polyhydric alcohol contains at least 3 carbon atoms and at least 3 hydroxyl groups. Preferred crosslinkers are those selected from the group consisting of allyl ethers of sucrose and allyl ethers of pentaerythritol, and mixtures thereof.

These copolymers are known as acrylates/C10-30 alkyl acrylate crosspolymers and are commercially available as Carbopol® 1342, Pemulen TR-1, and Pemulen TR-2, from B.F. Goodrich. In other words, examples of carboxylic acid polymer thickeners useful herein are those selected from the group consisting of carbomers, acrylates/C10-30 alkyl acrylate crosspolymers, and mixtures thereof.

Method of Using Hair and Skin Care Compositions

The hair care and skin care compositions of the present invention are used in conventional ways to provide the desired benefit appropriate to the product such as hair styling, holding, cleansing, conditioning and the like for hair care compositions and benefits such as moisturization, sun protection, anti-acne, anti-wrinkling, artificial tanning, analgesic, and other cosmetic and pharmaceutical benefits for skin care compositions. Such methods of use depend upon the type of composition employed but generally involve application of an effective amount of the product to the hair or skin, which may then be rinsed from the hair or skin (as in the case of shampoos and some conditioning products) or allowed to remain on the hair (as in the case of spray, mousse, or gel products), or allowed to remain on the skin (as in the case of the skin care compositions). By "effective amount" is meant an amount sufficient to provide the benefit desired. Preferably, hair rinse, mousse, and gel products are applied to wet or damp hair prior to drying and styling of the hair. After such compositions are applied to the hair, the hair is dried and styled in the usual ways of the user. Hair sprays are typically applied to dry hair after it has already been dried and styled. Cosmetic and pharmaceutical topical skin care compositions are applied to and rubbed into the skin.
